!!! Which codec do I need to watch these videos? A few of the videos have been coded with XVid. All the rest have been encoded with libavcodec "mpeg4" option using mp3lame as the audio codec. If you're a Linux user, you're lucky. [http://mplayerhq.hu/|MPlayer] contains everything you need and is completely free (pricewise and [http://www.fsf.org/philosophy/free-sw.html|rightswise]).%%% Just remember that if you decide to use a CVS version, you need to add libavcodec manually before compiling. If you're a Windows user, installing DivX and XVid codecs should help. If you download and install "ffdshow", both should work.
